Magnelis® ZM120 applications
While the primary application under consideration was the use of Magnelis® on cold formed sections used in light steel framing, Magnelis® ZM120 is already widely used to manufacture cable trays, flooring systems, indoor ventilation equipment, ceilings, walls and partitions, racking systems, profiled members, and opened and closed profiles.
Magnelis® can be applied to an extensive scope of steel grades, including steels for cold forming and deep drawing applications, as well as structural and high strength, low alloy steels.

Steel Construction Institute reports on Magnelis® ZM120 corrosion protection
A report from the Steel Construction Institute (SCI) describes their independent review of the performance of the Magnelis® ZM120 coating for corrosion protection. An innovative metallic coating that offers protection in the harshest environments, Magnelis® is a ZM (zinc-aluminium-magnesium) coating in accordance with EN 10346:2015.
Review of Magnelis® coating performance as corrosion protection
The SCI report details the performance of Magnelis® ZM120 coating against corrosion compared with traditional Z275 coating and includes the surface, cut edges, deformed elements, and welded tubes. This independent review and assessment was conducted via a wide range of testing, such as salt-spray tests according to ISO 9227, cyclic tests VDA 621-415 and ECC1, and outdoor exposure tests of up to 10 years.
Conclusions and recommendations
As a result of the performance review and assessment of research information, the SCI findings are as follows:
- Magnelis® ZM120 provides corrosion protection which is not less than the corrosion protection provided by Z275 coating.
- This conclusion applies to surface protection and to protection of cut edges.
- Magnelis® ZM120 is suitable for the same applications as the Z275 coating which is typically specified in UK and Irish construction.
- The design life predictions for the Z275 coating as stated in SCI publication P262 are also applicable to Magnelis® ZM120.
